Silky Caverns

Silky Caverns is a cave biome that is filled to the brim with cobwebs and also 'Silk blocks' acting as walls replacing stone & deepslate. No mobs other then Spiders & Cave Spiders are allowed to spawn here. For the sake of players with Arachnophobia maybe this biome is always concealed with Silk blocks, requiring players to break in on their own to explore it. Bane of Arthropods would be heavily encouraged...

On all sides of the cave there would be layers of cobwebs that can broken through to allow exploration. Silk blocks line the walls and has a chance to create cobwebs when a spider is standing on top of it, allowing renewable cobwebs. The tool for Silk blocks is shears or a sword, and can be picked up using silk touch. Silk blocks have a squishy noise when walked on.

Along the floor of this biome you can uncommonly find a 'webbed object' of various size. By using the Archaeology brush you can clean the webs off and reveal the object. You dont know what is contained inside until you clean the webs off. The minigame here would be cleaning off these webbed objects and uncovering loot, or even an entire mob that has been trapped inside (even hostile ones).

The spiders would pull explorers of all types here, the loot would reflect that, miscellaneous items, metals, lower tier tools & armor. However you can also rescue mobs such as: Villagers, Pillagers, Witches, Skeletons (without bows), Creepers, Zombies. The bigger webbed objects could even have an Iron Golem trapped.
